I checked it out for you. The scene happens somewhere around the end of Volume 9 of the manga when some black ghosts attack the city (I didn't have enough time to figure out why the ghosts attack in first place, though) and Zenki, Chiaki and Akira try to find a way to stop them. Ozunu makes the three heroes fight a wooden guardian to prove themselves and Chibi Zenki and Akira can't transform.

I did some research on my own on this, so the corresponding information should be in the folder, but my memory on this has faded and I don't have much time today, so that's all I can give you for now.
